Beetle infestation #763480

Asked July 23, 2021, 12:26 PM EDT

Is this an Elm Leaf Beatle? Just this week we've had an infestation outside our home in Arvada. Windows and along the top edges of the house. Have not had them in the past, what to do about them?

I think you're correct.  They seem to have become more common after a number of years of low abundance.  See http://extension.colostate.edu/topic-areas/insects/elm-leaf-beetles-5-521-2/.

Thank you.  All of a sudden, we’ve got a couple hundred all over the back and side, mostly up around the gutter and roof line..  I suppose I should look in our cottonless cottonwood.
